This project is located in Shanxi Province, China. The customer is one of old friends of GreatWall.  It has years of experience on desulfurization agent production. As early as 2016, the customer bought grinding mills from GreatWall to process limestone . Now, the customer decided to expand production scale. So in consideration of good performances of GreatWall's mills and considerate after-sales services, the customer chose GreatWall again without hesitation.Currently, this project has been put into operation.
